Tool table Main frame I (Fig. 1) is primarily of general pedwtal contourhaving upper portion at its sup- Porting face 2 providing dovetailguide-way 3 35 (Figs. 5, 7). Mounted on this face 2 is primary orauxiliary frame 4 having complementary fragmentary dovetail 5 forseating in the way 3. Dovetail section 6, coacting with fragmentarydovetail 5 is effective for definitely fixing the adjusted position ofthe auxiliary frame 4 through the medium of the guide 3 of the mainframe I. This dovetail section 5 mounts rack 1 (Figs. 1, 5) with whichcoacts pinion 8 on shaft 9 provided with handle l0. Accordingly,rotation of this shaft 9, by means of the handle Ill, clockwise, shiftsthe feed of the frame 4 to the right (Fig. 3); and counter-clockwise,reversely, or to the left. As the adjustment desired is obtained,handles ll (Figs. 1, 3, 7) may be rocked 180 and thereby each through ashaft I 2, held from iongitudinal movement by a set screw l3, to 'beeffective to shift an eccentric pin H, having thereon an eye I 5 of ascrew stem l6 anchored with the dovetail section 6. u

It is thus seen that with the arms or handles ll upward the dovetail isreleased or collapsed -so that the handle It may readily effect theshifting of the auxiliary frame 4 to the desired position relatively tothe main frame I. As such position is reached, a swinging of the armsdownwardly pulls the dovetail section 5, as guided by pin l5 (Fig. 6),into the complementary overhang section portion of the way 3, therebysnugly This frame 4 has ledge-providing seat portion l1 (Fig. 1)laterally from and parallel to the dovetail 5, 8. Assembled with thisframe 4 is frame section II at this seat l1. This frame section |8(Figs. 11, 12) has dovetail guide-way l9, into which extendscomplementary dovetail of secondary auxiliary frame 2|. This frame 2|has, through the depending dovetail-providing portion 20, internallythreaded eye'22 with which threaded stem 23 may engage. This stem 23 isprovided with collar 24 abutted by guide block 25 anchored with theframe section l8 (Fig. 2) by screws 26. From this shoulder 24' (Fig.11). protruding through this guide plate 25, is shaft 21 from thisthreaded portion 23. Set screw 28 through collar 29 anchors this collarto oppose the shoulder 24 and thereby holds this threaded portion 23 andthe shaft 21 fixed against longitudinal movement relatively to the framesection' l8, but free to rotate therein as actuated by handle 30,connected to this shaft 21 by set screw 3|. The angle of frictionbetween the threaded portion 23 with the eye 22 is suflicient to holdthe secondary frame 2| in the adjusted position.

Tool drive This secondary or auxiliary frame 2| has fixedly mountedtherewith by bolts 32 (Fig. 2) electric motor 33 having shaft 34carrying stepped V-pulley 35 in housing 36, mounted by bracket 31,carried by pin 38 from the frame l8. V-belt 39 from a selected step ofthe pulley 35 may extend to companion, oppositely stepped V-pulley 40(Figs. 3, 13). This V-pulley stepped section .or cone 40 is mounted onbearings 4|, and by bolts 42 is assembled with pinion 43 in mesh withgear 44 fixed with shaft 45 in bearings 46 carried within housingsection 41 fixed with housing section 41' as a part of the frame 4.

This housing section 41 is provided with bearings 48, 49, about sleeveor tube 50, about which tube 50 the bearings 4| are located. The shaft45 in the housing 41 has fixed therewith pinion 5| in mesh, as a speedreduction drive, with gear 52 keyed with the sleeve 50. This sleeve 50has interior taper terminus 53 projecting beyond the bearing 49effective as a rotary holder for substitutive tools. As such taperedsleeve side of the bearings 49, this sleeve 50 has shoulder 54.Oppositely thereto and about this sleeve 50 at the bearings 49 is nut 55threaded with the sleeve 58 and anchored by set screw 56 in adjustedposition with such sleeve to oppose the shoulder 54. This sleeve 50 isaccordingly held against longitudinal shifting relatively to the frame41' while free to rotate therein. Additionally, as to the bearings 48,there is nut 51 held by set screw 58 opposing the gear 52, and thusholding the drive for effective assembly in rotating this sleeve 58.

aims

The sheaves or stepped cone pulleys 35, 45, provide for changes of speedin this drive. These bearings 45 within the housing 41 are spaced fromsuch housing 41 and mounted by eccentric 58. This eccentric 58 hascoaction with the shaft 45 against the longitudinal movement of suchshaft due to nut having thread engagement with the shaft 45 adjacent thegear -44, and nut 5| having thread engagement therewith remote from thegear 44 and spaced from the pinion 5| by one of the bearings 46. Thislatter bearing 48 has held adjacent thereto by set screw 82 cap 53 withwhich handle 64 engages and is thus anchored with the eccentric 59. Thishandle 54 in horizontal position abuts pin 95 and thus holds theeccentric 59 in meshing relation for the gear 44 with the pinion 43 andfor the pinion 5| with the ear 52.

Upon rocking this handle 64 (Figs. 1, 13) upward or counter-clockwisethe eccentric 58 has its thicker portion relative to the shaft 45shifted from the side remote from the sleeve 58 toward such sleeve 50.This radially shifts this shaft 45 and its axis relatively to the axisof the sleeve 50 and uncouples the drive for the sleeve 50 as from thepulley 40 by shifting the gear 44 out of mesh with the pinion 43 and thepinion 5| out of mesh with the pinion 52. Thus, notwithstanding themotor 33 may be still running, it is practicable to disconnect thesleeve 50 and thus stop the rotation of this holder portion 53.

Adjacent the bearing 4| there is mounted about the sleeve 50 clutchmember 56 axially fixed to the sleeve 50 by key 61. This clutch member68 has toothed portion 68 which may be clear under overhang 89 of teeth10. This key 81 from the clutch member 66 and engaging the sleeve 65passes through sleeve element 1| having longitudinally thereon seats 12.Spring thrust pin 13 (Fig. 14) is a yieldable holding means for thisclutch member 68 axially as to the sleeve 50, for this sleeve element 1|is held against shifting relatively to the bearing 4| by collar 14threaded with the sleeve 5|! and anchored in threaded position by setscrew 16. Axial shifting of the clutch member 66, effecting radialmovement of the pin 13 against the resistance of spring 11, may, inmovement away from the pulley 40, bring the toothed portion 68 into meshwith the toothed portion 19 and thereby directly clutch this drivingpulley 40 with the driven sleeve 50.

At the taper portion 53 in the sleeve 50, there may be placed a toolholder or collet 18 held against relative rotation by key 19. Thiscollet or holder 18, as provided with externally threaded portion 80,has such engaged by threaded portion 8| on inner tubular member 82within the sleeve 50. This tubular member 82 passes beyond the remoteend of the sleeve 50 and through thrust bearing 83 to have hand wheel 84fixed therewith. Rotation of this hand wheel 84 relatively to the sleeve58 may draw the collet 18 into binding position at the taper 53 orrelease such for thrusting axially outward clear of this sleeve 50. Inthe event a smaller tool or other element be centered by the collet 18,such minor element 85 may have threaded engagement with internallythreaded portion 86 of supplemental inner tube 81 extending through thetube 82 and having hand wheel 88 thereon spaced from the tube 82 bythrust bearing 89. Accordingly, these hand wheels 83, 89, provide in onedirection of rotation a longitudinal or axial shortening in pulling thecollet holder or tool into anchored position with the rotary drivingsleeve 50, while the reverse direction of rotation frees such colletholder or tool from such axial clamping so that such may be readilyremoved.

There is, accordingly, for this rotary element or holder, the main frameI, primary or auxiliary frame 2, with its section I8, and rotarysecondary auxiliary frame 59. There is provision\ herein for nicety inranges of adjustment. The handle 39 (Fig. 1) coacts in shifting themotor 33 toward or from the sleeve or secondary auxiliary frame 59 ineffecting the desired adjustment for the driving belt 39. This primaryauxiliary frame unit has its adjustment relatively to the frame Ieffective through the handle I9.

When occasion arises for operating the hand wheels 84 or 88, it isdesirable that the frame or sleeve 99 be anchored against rotation. Tothis end, the housing 41' is provided with closure or end 99 carryingboss 9| (Figs. 3, 4, 13) in] which, against overhang 92, is spring 93opposing shoulder 94 of pin having cross pin 96 adjacent knurled handle9I. With the shoulder or head 94 in the boss 9'I against the spring 93,the handle 91 may be pulled and angularly shifted to bring the pin 98clear of slot 98, and this head 94 is thus held retracted from notches99 in plate or flange I99, fixed with the pinion 43 and assembled withthe step pulley 49 by the bolts 42. With this head 94 engaging the notchthis sleeve 59 is held against angular rotation and the manual operationfor assembling or disconnecting a tool through the medium of the wheels84, 89, may then be readily accomplished. As such work is effected. itis only necessary to engage the handle 91 withdrawing the pin 95 againstthe resistance of spring 93 and rotate so that the cross pin 98 is inthe slot 98 and the head 94 is in the selected notch 99.

Work table This main frame I has upwardly extending dovetailed guide I9I(Figs. 1, 2, 8) in an intersecting direction or toward the horizontallyextending guide across the top of this pedestal base or main frame I.This dovetail guide I9I is embraced by primary auxiliary work tableelement or frame I92 having fixed therewith wedge guide element I93 andspaced therefrom by clearance I92 is opposing adjustable wedge I94,thereby effecting embracing of this dovetail I9I from this primaryauxiliary frame I92. This primary frame I92 has slots I95 (Fig. 19) withwhich engage bolts I98 extending to the wedge I94, thereby effective toadjust such wedge I94 along the beveled face I9'I of the auxiliary frameI92. This is an effective lost motion provision or takeup, insuringnicety of adjustment for the auxiliary frame W2 against even vibrationduring working operation.

This upwardly extending dovetail guide I9I has the work faces coactingwith the edges I93 protected against foreign material, especially metalturnings, borings, filings or other particles. To this end, fiber orpyroxylin block I98 (Figs. 8, 9) of V- or wedge-form, has tapered facesI99 so that there is effective line contact at the upper side of suchblock as to the wear faces, and this adjustment is maintained yieldablyby spring II9 held in position by block II I, anchored by screw II2clear of the .wearblock I98, and screw II3 through opening H4 in thewear block I98. This is an effective wiper, maintaining the guide facesclear of material which might otherwise score or detract from the nicetyof guide operation.

ly inclined shaft I23 having bearing I24 in tubu-' lar portion I 25.This portion I25 has set screw I28 positioning sleeve I2I carryingoutwardly from this portion I25 bushing I28 centering this shaft I23adjacent handle I29. Accordingly, by rotating this handle I29, there iseffected rotation of the nut I29 held against axial movement relativelyto the auxiliary frame I92. This means that this nut effects travelalong this fixed screw H9 and the member or frame I92 is thus adjustedalong the pedestal I for greater or'less clearance as to the base H5.

The auxiliary frame I92 has dovetail horizontally-extending guide or topportion I39 (Fig. 1). With this coacts secondary auxiliary frame I3Ihaving fixed overhang I32 and opposing adjustable overhang I33completing assembly with the dovetail I39. Bolts I34 through slots I35(Figs. 2, 21) in drop L-shaped or flange portion. I36 of the frame I arebolts which directly engage the adjustable overhang I33. The slots I35,as

the bolts I34 are slackened 011, permit shifting of this overhang I33longitudinally of the guide I39 for taper side I31 (Fig. 25) so to coactwith the L-shaped holder I36 that there is provision for clearance orclearance take-up as to the guide I39 for this frame I 3i, thus makingpossible retention of desired Working nicety for holding againstvibration even in machine operation. This secondary auxiliary frame I3Iis so directed by the guide I99 that it may move horizontally relativelyto the primary auxiliary frame I 92.

Occasion is here taken against material as from the work acting on theguide surface. To this end, the frame I3I has inclined way I39 (Figs.21, 24, 27) in which is disposed zig-zag spring strip I39 to thrustfiber or pyroxylin bar I49 from the member I3I down toward the guide I39so that its inclined face I4I may be an efiective wiper againstdeleterious foreign material. Accordingly, in this clearing actiontravel of the frame I3I toward the guide I9I, there is provision forfree spilling in the clearance I92.

This secondary auxiliary frame is provided with wedge-shaped fixed guideI42 (Figs. 21,

27) and companion opposing adjustable guide I43. Flange I44 from theauxiliary frame I3I has slot I45 (Fig. 25) in the plane of the angularface through which extends the bolt I46, thus adjusting this wedge I43as shifted longitudinally of the holder I44 to render inclined way I41effective as a take-up to provide such reduced amount of clearance asmay be desired for snugly locating dovetail guide I48 fixed withtertiary auxiliary frame I 49.

These primary, secondary and tertiary frames, with their generalintersecting-direction guides, thus effectively provide for threedimensional location of a-holder to be carried thereby, whether for toolor work. This tertiary auxiliary frame I49 is shown provided with keyslots I 59 (Fig. 21) in supporting face I5I. This supporting face orplane may thus have T-shaped means I52 therein to effect assembly withholder element I53 (Figs. 21, 28). This member I53 has on diiferentsides thereof guide-ways I54, I55, I54, in a plurality of directions fordifferent dimensions, herein shown as three dimension ranges.Accordingly, this vise block may serve as a chuck in three ways,definitely positioning work upon a three-way directed work tablerelatively to a two direction rotary tool.

This holder element I53 as herein, may form one of the elements of avise blocks and beef L-form with riser portion I51 through which mayextend screws I58 to mount clamping face I59 as one of the jaws of thevise block opposing supplemental block I66 assembled by bolts I6I havingheads I52 (Fig. 30) in ways I63 .of the element I53. There is thusprovision for locating or adjusting the element or block I66 relativelyto the element or block I53, and as so adjusted toward and from the faceor jaw I59, nuts I64 may be brought to locking position.

Between these screws I6I there is key way I95 (Figs. 28, 30, 31) in theblock I66 for key I66 to protrude into a way I63. This key I66 isanchored with the block I66 by screws I61. This key I66, as projectinginto the way I63 between the bolts I6I, is an effective aligning meansagainst any regular positioning of the block I66 relatively to thedirection which it is desired to have such block take as determined bythe way I63.

This block I66 has jaw I68 .(Figs. 28, 31, 32) mounted by screws I69with minor block I16 of L-form, which is adjusted relatively to themajor block I66 by screws I1I through the block I66 and abutting theupstanding portion of this L or minor block I16. This minor or L-blockI16 has horizontal extension portion with slot I12 therein. In this slotis screw I13 engaging shoulder I14 of the block I16. This screw entersthe block I86 and is thus an assembly effecting means between the minorand major blocks so that this minor block I16, as thrust by compressionhelical spring I15, may cause the jaw I68 yieldably to engage work asbetween this jaw I 68 and the jaw I59 within the limitations permittedby the screw I13. Semicylindrical block I15, adjacent the shoulder I14,provides bearing for one coil of the spring I15, while semicylindricalhead I15" is an abutment for the opposite end of this spring I15.

Nicety of placing work herein is of importance, and between therespective frames there is located definite relation-disclosing means inthe form of scales or graduations I16 (Figs. '1, 3, 21, 34). Inproximity to check a specific position on such scale, a companion memberis provided with guide-way I11 in which is located frame I18 mountingbarrel I19 having annular graduations I86 to thrust stern I8I as tolineal graduations I82. There is thus definite positioning of this stemI8I relatively to stem I83 in this frame I18 located by set screws I84against casual disturbance, for these respective set screws I84 maycarry spring clips I85 resting on this rod I83; and this rod I83 may bemanually axially shiftable by using the head I86 in providing anabutment, say as against work.

Mounted on this rod I83 is frame I81 for angularly directed microscopesection I86 as to main microscope section I89, thus directed for minuteinspection of calibrations for positions between the frames sodefinitely complementary to the graduations I86, I82. This means that,with the set-up herein and the close connections to avoid play, linealdimensions of as close as one ten thousandth of an inch may be reliedupon and Feed drive In addition to the tool operation for the rotaryholder there may .be a feed or movement in operation for supplementaltool or work. To this end, in the main frame I (Fig. 2) there may beshelf I96 placing base I9I, upon which is mounted the secondary frame 2|carrying motor I92 having shaft I93, having fixed thereon cone orstepped V-pulley I94, from which extends vbelt I95 in housing I98 tooppositely placed or V-cone pulley I91 in bearings I98 of frame sectionI99. This stepped cone pulley I91 is splined on shaft 266 extendingthrough bearing 26I in frame section 262 within the main frame I.Fixedly mounted on this shaft 266 adjacent the bearing 26I and betweensuch bearing and the cone pulley I91 are gear 263 and pinion 264. Asprotruding within the frame I from the frame section 26I, this shaft 266has ring collars 265 thereon as a rack in mesh with pinion 266 on shaft261 (Fig. 15). This shaft 261 extends through guide ears 268 of theframe section 262 and thence outward of the frame I on the side towardthe controller station or to the left of Fig. 1. Upon this shaft 261 asthus protruding from the frame, there is mounted handle 269, connectedto the shaft 261 by pin 2I6. About this shaft 261 between the handle 269and the frame I is a collar 2I I anchored by screws 2I2 with this frame.

This collar has headed pin 2 I3 normally thrust by spring 2I4 and actingagainst shoulder 2I5 in the collar 2 to have the head of this pin 2I3enter a seat ,2I6 in the shaft 261. These several seats 2I6 (Fig. 16) inthe shaft 261 locate this shaft angularly in different positions forholding the shaft 266 in intermediate or nonconnecting position (Fig. 2)or for shifting the gear 263 into mesh with gear 2I1 for one speed ofdriving, or for shifting in the reverse direction to bring the pinion264 into mesh with gear 2I8 for a lower speed of driving for shaft 2I9parallel with the shaft 266 and extending in the frame I from the framesection 262, and thence outward of this frame I. The shaft 2I9 extendsinto housing box 226 (Fig. 1'1). This shaft 2I9 in this box 226 carriesworm 22I in mesh with worm wheel 222, splined to vertically-extendingshaft 223 (Figs. 2, 1'1, 21). This shaft 223 is thus movable with theprimary frame I62 relatively to the frame I because this shaft 223 isfixed with such frame I62 bearing box 224.

In this bearing box 224 bevel pinion 225 is in mesh with bevel pinion226 on horizontally-extending shaft 221 extending from this primaryauxiliary frame I into secondary frame l3I. This shaft 221 has splinedportion 228 (Fig. 19) extending through shiftable clutch member 229,keyed to rotate therewith. This member 229 is engaged by arm 236 mountedby nut 23I on rod 232 extending to rack portion 233 in mesh with pinion234 (Figs. 19, 22). This pinion 234 is on shaft 235 having pin 236fixing therewith fork 231. Pin 238 through the fork 231 rockably mountshandle 239. Spring 246, through the action of pin 24I, normally locksthis handle 239 so that recessed handle extension 242 engages a lug 243(Figs. 22, 23). At the mid-lug 243 the clutch 229 is unclutched andthere is no transmission of the feed drive from the shaft 221.

However, in shifting the handle 239 to be clear of central lug 243 andthence rocking to another (Fig. 19)

lug 243, this shaft 234; the clutchmember 2 maybe thrown and locked toengage sleeve 244 This sleeve is mounted in bearing 245. Fixed with thesleeve 244 is bevel pinion 246 in mesh with bevel pinion 241 keyed withshaft 248, mounted in bearings in the secondary auxiliary frame I3 I.Fixed with this shaft 246 remote from the bevel gear 241 is bevel pinion249 in mesh with bevel pimon 250, keyed to shaft I parallel to the shaft.221. This shaft 25I is accordingly actuated at a slow speed of rotationand has threaded portion 252 engage internally threaded eye 253 on stem254 (Figs. 19, 27) mounted in the auxiliary frame I02. This slow speedpower drive for rotating this shaft 253,

or if so actuated by handle 255, effects a feed or shifting of thissecondary auxiliary table III horizontally or relatively to the verticalmovement of the primary table I02.

In the event the shifting of the handle 239 be in the reverse directionfrom neutral so that the clutch member 229 engages sleeve 256 (Fig. 19),there is driving rotation of spiral pinion 251 (Figs. 19, 21, 25). Thispinion 251 is in mesh with spiral gear 258 splined on shaft 259. Thisshaft has threaded portion 260 engaging internally threaded eye 26I ofstem 262 fixed in the secondary frame I3I. Accordingly, the slow speedpower feed rotation for this shaft 259, or manual rotation thereofeffected by handle 263, effects a shifting of the tertiary table I49.

Near the rear left of Fig. l in convenient position for the variousparts of the machine which may at times require manual attention, isoperator station where there is located plate 264 on the frame I (Fig.These provide starting push button 265 for the motor 33 controlling thetool rotation.

Push button 266 may effect reversal of such rotation for the motor 33 ascut in by the switch 265. Push button 251 may be effective for startingthe feed motor I92 for a speed of driving either as adjusted from thehandle 209 or by shifting the belt I95 at various positions on the conepulleys IM, I91. The direction of feed for the selected secondary ortertiary table or auxiliary frame is controlled by reverse effectingpush button 268. Safety switch 269 may be used for complete machinecut-out and line power drop which shuts off all current and requiresmanual re-starting for the machine.

The rotary holder for the tool, accordingly,'

has a range of axial travel for different overhang relations as to thework tables and accordingly, effectiveness for locating feed as well asdifferent speeds of such feed. The different direction tables orauxiliary frames for work or tool, whether complementary or for othercooperation, are effective in three dimension placing so that there isrange for handling work in full requirements for placement as accessiblefrom the rotary holder axis in the event there is importance forapproximately jig relationship in other planes transversely of the axisof the rotary holder. The ways I54, I55, I56, permit definiteorientation of this vise with fineness of fully required accuracypossible from delicate jig means, due to the graduation readingspossible for determining location and the fact that such location iseffective with elimination of any and all play of any degree which mightaffect accuracy in the product. The direction of the guide-ways in theultimate work holder or vise are shown (Fig. 28) as in the three planesand at right angles to each other. Special work may warrant departure indirection of ways as angular ways 210, 2" (Fig. 33).
